A filler material is disposed within the gap. The filler material responds to pressure such that the filler volume is reduced by less than 5 volume percent at greater than 500 MPa pressure and at greater than 500° C. temperature. One or more heating elements are disposed in the gap. The heating elements are in thermal communication with the inner tube.
